I am not a huge fan of OSX, but I have to support it for users at my job. I’ve had several people recently ask me how to permanently disable the bouncing icons in the dock/taskbar. The solution is simple. Open a Terminal window and type the following commands:
$ defaults write com.apple.dock no-bouncing -bool TRUE
$ killall Dock
This will permanently disable the jumping and bouncing icons in the dock bar. To re-enable the bouncing, change the above command’s ‘True’ argument to ‘False’
Have fun with that.
